Rug Care Tips: Preventing Mildew and Dry Rot in Rugs

When rugs stay wet too long, they become mildewed and, eventually, suffer dry rot. The classic example is dry
rot caused by a potted plant placed on a rug. The typical result is a horribly rotted circular area in a
carpet that is otherwise in good condition. Don’t even think about putting a potted plant on a rug. No
matter how clever you are or if you use a glazed pot or saucer, it may not work. Whether you put a vapor
barrier between the saucer and the rug, the rug will get wet. Most importantly, it will stay wet. And
unbeknownst to you and will become a rotten mess in an area about one foot in diameter.

Another typical situation comes up
when rugs are stored poorly. Therefore, when they are stored in a garage and become wet without anyone
realizing, this can become an issue. Even though dry rot is not inevitable in such cases, a mildew smell is,
and sometimes the smell of mildew simply cannot be removed. I have seen several occasions when moisture
under a house has caused rugs on the floor above to mildew.

Caring For Your Rugs

Please do not worry needlessly, though. A little water on a rug, or even a
lot of water, will not cause it to mildew unless the rug stays wet too long. For instance, when a rug is stepped
onto after a shower or bath rarely are hurt by water because they have time to dry out between bath times. And
don’t panic if you spill a glass of water on a rug. Lastly, just dry it as well as you can with
towels.

Unfortunately, besides causing mildew and dry rot, water sometimes causes dyes in rugs to
bleed or run. All you can do in this situation is to get the rug dry as soon as possible and to send it to an expert rug washer. If a rug is just a little wet, as
from a spilled glass of water, do what I suggested above. Merely soak up as much water as possible with a towel
or paper towel and everything will probably be just fine. If you are worried about the floor underneath, elevate
the wet spot until it dries.

When All Else Fails

A rug that is thoroughly wet is another matter. The goal is to dry it before
it mildews in about four or five days. If you have a Shopvac or other vacuum that will take in water, vacuum out
as much water as you can. If you have sunlight and a place to lay the rug, open it and let it finish drying
outdoors. Or, if you know that the rug is dirty as well as wet, dry it enough so that you can get it to an Oriental rug cleaning specialist.
